Hypotension complicating regional blockade Leonie Watterson Hypotension is the most common complication of regional blockade. A systolic blood pressure of less than 100 mmHg, or a fall of greater than 30% should be considered significant (1). Hypotension usually results from the physiologic effects of sympathetic blockade on the cardiovascular system and will be exacerbated by aortocaval compression ( Figure 28.1 Chapter 28 ) or reverse Trendelenberg positioning. It is important to bear in mind the other possible causes of a low blood pressure in the parturient who has a functioning epidural block ( Table 6.2 The incidence of hypotension can be markedly reduced by the employment of preventative measures. A reduction from 79%-100% to 0-10% has been demonstrated as a result of the use of the left lateral position, intravenous preloading, and vasopressor therapy (2, 3). The management of hypotension should be approached in three stages: 1. Commence supportive measures to stabilise maternal blood pressure: ( Table 6.1

44. Hypotension . The pressure of the blood...... hypotension. Definition. hypotension is the medical term for low blood pressure. http://www.healthatoz.com/healthatoz/Atoz/ency/hypotension.html

Encyclopedia Index H Home Encyclopedia Encyclopedia Index H Hypotension Definition Hypotension is the medical term for low blood pressure. Description The pressure of the blood in the arteries rises and falls as the heart and muscles handle demands of daily living, such as exercise , sleep and stress . Some healthy people have blood pressure well below the average for their age, even though they have a completely normal heart and blood vessels. This is often true of athletes who are in superior shape. The term "hypotension" is usually used only when blood pressure has fallen so far that enough blood can no longer reach the brain, causing dizziness and fainting Causes and symptoms Postural hypotension is the most common type of low blood pressure. In this condition, symptoms appear after a person sits up or stands quickly. In normal people, the cardiovascular system must make a quick adjustment to raise blood pressure slightly to account for the change in position. For those with postural hypotension, the blood pressure adjustment is not adequate or it doesn't happen. Postural hypotension may occur if someone is taking certain drugs or medicine for high blood pressure. It also happens to diabetics when nerve damage has disrupted the reflexes that control blood pressure. Many people have a chronic problem with low blood pressure that is not particularly serious. This may include people who require certain medications, who are pregnant, have bad veins, or have arteriosclerosis (hardening of the arteries).

45. Orthostatic Hypotension Orthostatic hypotension. Definition. Orthostatic hypotension is an abnormal decrease in blood pressure when a person stands up. http://www.healthatoz.com/healthatoz/Atoz/ency/orthostatic_hypotension.html

Encyclopedia Index O Home Encyclopedia Encyclopedia Index O Orthostatic hypotension Definition Orthostatic hypotension is an abnormal decrease in blood pressure when a person stands up. This may lead to fainting Description When a person stands upright, a certain amount of blood normally pools in the veins of the ankles and legs. This pooling means that there is slightly less blood for the heart to pump and causes a drop in blood pressure. Usually, the body responds to this drop so quickly, a person is unaware of the change. The brain tells the blood vessels to constrict so they have less capacity to carry blood, and at the same time tells the heart to beat faster and harder. These responses last for a very brief time. If the body's response to a change in vertical position is slow or absent, the result is orthostatic hypotension. It is not a true disease, but the inability to regulate blood pressure quickly. Causes and symptoms Orthostatic hypotension has many possible causes. The most common cause is medications used to treat other conditions. Diuretics reduce the amount of fluid in the body which reduces the volume of blood. Medicines used to expand the blood vessels increase the vessel's ability to carry blood and so lower blood pressure.

46. Low Blood Pressure (Hypotension [Neurally Mediated, Orthostatic, Postural]) Low blood pressure (hypotension) is the medical term for a blood pressure (BP) of less than 90/60. Some chronic forms cause symptoms http://www.heartcenteronline.com/Low_Blood_Pressure.html

Low Blood Pressure (Hypotension) Low blood pressure (hypotension) is the medical term for a blood pressure (BP) of less than 90/60. Some chronic forms cause symptoms and require diagnosis and treatment (e.g., orthostatic hypotension, neurally mediated hypotension, postural hypotension and neurogenic orthostatic hypotension). Usually, borderline-low or slightly low BP readings show no symptoms and require no treatment. Low BP can be a sign of good health in some people with no symptoms (e.g., athletes), indicating that their hearts, lungs and blood vessels are well conditioned and in good working order. On the other hand, low BP may also be a warning signal, especially to the elderly, that something is wrong with their health or health care treatment. Hypotension in the elderly can cause neurological and heart-related problems. Low blood pressure symptoms may include dizziness or lightheadedness; blurry vision; lack of concentration; nausea or upset stomach; muscle weakness; fainting (syncope); rapid, weak pulse; cold, clammy skin; rapid, shallow breathing; fatigue; and/or headache. Causes of hypotension are not always clear. It may be associated with one or more of the following: Dilated (wide) blood vessels; weakened heart contraction; obstructed blood flow (e.g., due to defective heart valves); overdosage of

The Blood Pressure Center Blood pressure (BP) is a measure of the force, or tension, of the blood against the walls of the arteries. BP is expressed as systolic pressure over diastolic pressure. High blood pressure (hypertension) stresses the heart and can contribute to coronary artery disease, heart attack and stroke. Low blood pressure (hypotension) can cause dizziness and fainting (syncope). Normal BP for adults is considered to be in the range of 120/80 millimeters of mercury. Generally, a BP reading above 140/90 is considered to be high for adults, and reading under 90/60 is considered to be low for adults. Hypertension has been associated with a variety of significant health risks, including an increased risk of heart disease and aneurysm. The condition is especially deadly among African-Americans , who tend to be diagnosed at younger ages and with higher BP than other ethnic groups. Women are also encouraged to discuss with their physician the increased risk of hypertension that results from taking birth control pills. Currently, an estimated 10 to 15 percent of school-age children have hypertension.

Ask the Doctor Q: Hypotension blackouts Every time I get up lately I seem to black out. I can normally keep it under control but lately it's made me collapse - is this anything I should be worried about or is this normal? Deborah 19 Dr Trisha Macnair responds The most likely cause of your 'blackouts' is a condition called postural hypotension. When you go from lying down to standing up, your blood pressure drops very low, probably because your nervous system is a bit slow in telling your heart and blood vessels to work harder in order to pump your blood around against the effects of gravity. When your blood pressure is low not enough blood reaches your brain and you then feel faint and collapse. This is usually harmless, although if you fall down there is the risk that you may hurt yourself, and older people sometimes break their bones this way. In the rest of Europe, a low blood pressure is taken seriously. There it's often linked to a variety of symptoms, and is frequently treated with drugs. But in the UK, we tend to think that generally it is healthy to have a low blood pressure - and it's rarely treated.
